“…Materials exhibiting low interfacial toughness (LIT) with ice represent a paradigm shift in how the adhesion between ice and a surface may be reduced, especially large (>cm) iced interfaces 45 , 46 . LIT materials minimize the strain energy necessary to propagate an interfacial crack between the ice and surface, enabling size-independent de-icing, i.e.…”

Ice accretion causes problems in vital industries and has been addressed over the past decades with either passive or active de-icing systems. This work presents a smart, hybrid (passive and active) de-icing system through the combination of a low interfacial toughness coating, printed circuit board heaters, and an ice-detecting microwave sensor. The coating’s interfacial toughness with ice is found to be temperature dependent and can be modulated using the embedded heaters. Accordingly, de-icing is realized without melting the interface. The synergistic combination of the low interfacial toughness coating and periodic heaters results in a greater de-icing power density than a full-coverage heater system. The hybrid de-icing system also shows durability towards repeated icing/de-icing, mechanical abrasion, outdoor exposure, and chemical contamination. A non-contact planar microwave resonator sensor is additionally designed and implemented to precisely detect the presence or absence of water or ice on the surface while operating beneath the coating, further enhancing the system’s energy efficiency. Scalability of the smart coating is demonstrated using large (up to 1 m) iced interfaces. Overall, the smart hybrid system designed here offers a paradigm shift in de-icing that can efficiently render a surface ice-free without the need for energetically expensive interface melting.

“…[28] Mohseni et al found that quasicrystalline coatings show excellent ice repellency even after being abraded, scratched, heated, UV-irradiated, and exposed to chemical contaminations, which are promising for real outdoor anti-icing application (Figure 3f). [59] Besides, Boinovich et al proposed a strategy by combining both laser processing and deposition of fluorooxysilanes to overcome main drawbacks and improve resistance to destroying atmospheric impacts. [60] In short, various rational designs (i.e., surface textures, preparation methods and anti-icing strategy based optimizations) have been developed to enhance the durability of passive AIM such that the AIM can be utilized for a long-term use in the outdoor anti-icing application.…”

Ice accretion on exposed surfaces is unavoidable as time elapses and temperature lowers sufficiently in nature, causing detrimental impacts on the normal performance of devices and facilities. To mitigate icing problems, both active de‐icing and passive anti‐icing materials (AIM) have been utilized. Traditional active anti‐icing methods suffer from energy consumption, low efficiency and high cost, while passive AIM meet the challenges of improving mechanical durability and maintaining low ice adhesion strength during icing/de‐icing cycles. Recently, new AIM are rationally designed by the combination of passive anti‐icing and active de‐icing, exhibiting efficient, reliable and energy‐saving properties. The conceptual idea is that passive AIM only need to reach a certain value of ice adhesion strength (i.e., τice<100 kPa) instead of achieving lowest ice adhesion strength, and simultaneously combine with active de‐icing techniques (i.e., electro‐thermal and photo‐thermal stimulus) to realize ideal all‐weather anti‐icing/de‐icing. In this review paper, the authors provide a brief introduction to passive AIM, and mainly focus on recent advances in the electro‐/photo‐thermal promoted AIM in terms of anti‐icing/de‐icing mechanisms, challenges and perspectives. The new conceptual anti‐icing/de‐icing strategy will inspire the rational design of the state‐of‐the‐art AIM in future and provides practical solutions to mitigate outdoor anti‐icing/de‐icing problems in daily lives.

Ice accretion has detrimental effects on a wide range of sensitive engineering structures, especially those adjacent to or within the ocean. Here the effect of salinity on the adhesion of ice to different surfaces is investigated over a range of sub‐zero temperatures. The saline ice adhesion strength is found to decrease with the increasing salinity on all surfaces tested. The presence of thermodynamically stable brine at temperatures above −21.2 °C is found to drastically lower the saline ice adhesion strength of essentially all surfaces through a lubrication effect. At −25 °C, below the eutectic temperature between H2O ice and hydrohalite (NaCl 2H2O), high adhesion is observed. For smooth surfaces, hydrophobicity is effective at lowering the saline ice adhesion strength, and a hydrophobic silicon wafer exhibited a saline ice adhesion strength of 2.4 ± 1.8 kPa at −10 °C with 1 wt% NaCl. The adhesion of real frozen seawater differed from the NaCl solutions, where an adhesion strength ≈12 kPa is observed even at −25 °C. Given the strong adhesion of ice to marine infrastructure, the results here demonstrate how temperature, salinity, and surface characteristics must be considered when designing materials that can mitigate the icing of marine infrastructure and vessels.
